Giant's Drink (boon)

 is one of the boons in Mobius Final Fantasy. It increases the maximum HP of a character by 50% (rounded up). So if a character has 20,000 HP, it will be raised to 30,000.

Players can receive damage and heal as normal while this is in effect, back to full (enhanced) HP. When it wears off, remaining HP stays put, up to the player's normal maximum HP. (extra HP - or damage - is dropped)

This stacks with other boons such as or, additive in percentages from base HP.
